文摘
For the first time, the use of a membrane based copper ferrocyanide loaded sorbent for removal of Cs+ from neutral aqueous solution is reported in this work. The results indicated high Cs+ exchange capacity (1.75?mmol/g), large distribution coefficient, as well as fast absorption of the cation in the membrane. The membrane, inspite of presence of other metal ion, exclusively absorbed 137Cs from a simulated nuclear waste solution, though the absorption rate is affected due to their presence. This composite membrane showed promising properties for Cs+ removal from nuclear waste solution.
